Application filed November 18, 1907. serial Noa402,082.

.in the countyof Green and State of. Wisconsin, have invented a new and useful Machine, of which the following is a spec' cation. This invention relates to filing machines anditsobject is to provide an-endless file particularly designed for inside work such as the inner faces of dies and unches. Anot or object is to provide a e made up of sections of novel form and arranged in a novel manner so that filings and other particles canrnotbecome 10 ed between the sections and thus hold them out of proper alinement during the operation of the file.

Another object is to provide a-file made up of sections so shaped as to' produce -a con-.

tinuous unbroken surface at the point'of use. r

With these and other objects in view the invention consists of certain novelfeatures sections. Each block has its ends beveled .45

of construction and combinations of parts which will be hereinafter more fully described and pointed out inthe claims. 1 i

In the accompanying drawings is shown .the preferred form of the invention.

In. said drawings: Fi tion of a machine embo ying the presentimprovements, a portion thereof being ,removed. 2 is an enla ed longitudinal 'section through a portion of t efile and showing the joint therein. 3-is a face view of a portion of the file. Fig. 4 1's an enlarged transverse section through a part thereof.

Referring reference, 1 and 2-des1 ate upper and lower wheels or on w 'ch is mounted a belt 2'- preferably formed of aflexible strip of steel. This belt seated throughout 'its le h within ooves 3 formed. 0 "tudi .n y within b ocks 4 constituting t e file and l in parallel lanes and is fastened to the be t preferably y means of a screw 5 whichenters the grooved face of the block adjacent one end. The blocks are'all. arranged so as to abut when in alinemellt so that their outer or working faces will be continuous and no s aces Will be formed be-' tween them and within which-filings or other particles can accumulate. The ends of the e 1 is a side eleva-' "cated that the outer pliy to the figures by characters ofbelt 2 are engaged by one of these screws as indicated at 6 in Fig. 2 so that by remo,v-

mg saidscrew the two ends can be se arated and the belt inserted through a ho ow ob-.

i'ect the interior of which is to be filed. By

apping the ends of the blocks as shown and described said blocks become self-bracing when in alinement so as to practically reventsaggingor g ving when subjecte to transverse ressure.

'. In use w eels or drums 1 are mounted in suitable supports and in Fig. 1 one form of support has een shown, the same consisting a base 7 upon which the lower wheel is journaled anda bracket 8 in-which the upper wheel is journaled, said bracketbein'g carried by a standard 9. A work holding table 10 extends from the standard and between the-wheels and has openings through which the file extends, and if. desired, bracing or igTuide blocks 11 may be disposed back of the d1 d h hm rflsh 1i may be. 'soseuontemac'eortep ose' at t.

same is-setgin riiotion by any suitable mechanism, notshown, f the parts beln so 10- a of thefile move downward as indicate by 1, and .the ends of the sections 4 will be mclined downwardly and rearwardly. When the arrow in Fig.

work is placed on the table 10' and rcssed against the file it will be successivey contacted by the-blocks or sections 4 and as the ends of these sections abut and are inclined in the manner shown and described a continnous unbroken face is presented to thework and the ends of the sections are revented from biting into the. work' as wou d be the case if they were rectangular and s aced apart. Should it be .desired to use the e for the work after which the belt ends can be resecured together; a It is of course to be understood that the file sections can be of any de- I sired contour and can be used fordifferent classes of work. Any suitable means not shown may be used in connection with the machine for blowing dust from the table 10 so that it will not interfere with the work.

What is claimed is: 1. A file com rising a belt,-and a plurality of longitudinally channeled abrading sections each secured adjacent one end to the belt, said belt being mounted within the channel and the ends 'of the sections being beveled and disposed to contact when in aliuement.

2. A file comprising a belt, a plurality of abrading sections having longitudinal channels in one face constitutlng seats for the belt,

15 each section being secured adjacent one end abrading sections. a

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two Witnesses.
